_ N
Cartons have been widely used for packing fruits and other things ~o be shipped or stored. But it tal~es time to staple the carton folds together and it is wasteful because they are not recoverable and reusable. Furthermore, cartons are not strong enou~h for shipping in stack. It is often the case that the contents in the cartons being stacked by other cartons are damaged. To inspect the contents, they m~s~ be taken out one by one or layer by layer. ~ter inspection they must be packed back. So using cartons is not only a waste of money but also a waste of time and laborious. In the past years, the inventor himslef used about S,000 cartons a year for pac~ing fruits. At the current market price of $1.5 per carton, the total cost was $7,500 enough for 255 cartons of fruits. The amount would be terribly huge for the cartons used in the whole country.
According to the inventor's statistics, the cost of car~ons almost accounted for more than 50 perccnt of the sale amount of fruits a farmer had harvested. So if a stron~, collapsi-ble, recoverable and reusable container is developed to replace cartons, it would save the farmer a lot of money, time and trouble.
In view of this, the inventor studied hard with some intimate friends to make improvements and developed this invention.
So the main object of this invention is to provide a callapsible crate which has high compression strength to ensure safety of shipping and storin~.
Another object of ~his invention is to provide a collapsible crate which is recoverable and reusable so as to save money.

~ s shown in Fig. 1, ~he collapsible plastic cra e comprises .~ ro~t sidc plate 1, a back side plates 2, a left side plate 3, a r ght side ?'.ate 4, a top lid plate 5, a S bottom plate 6, seven knuckle pins 7 in same dlameter, and two tub~ ar connecto~s 8. The front side plate, has leftward spaced sockets 1~ on the left edge, backward spaced sockets 11 on the right edge, two projec~ions 12, 13 on the top edge, two small ho7es 14 ^n the top edge for tyin~ the top lid plate ~ with a wire, a hook lc and a lug 16 in the middie of the bottom edge and two slots 17 in the same edge near the corners. The said lug 16 has a slot 161 for the proiection 62 to fit in for the purpose to strengthen the binding. The back side plate 2 has forward spaced sockets 20 or the left edge, rightward spaced sockets 21 on the right edge, two notches 22 at the top edge to acco~modate the two tubular connectors 8, two indentures 23 at the corners, two forward spaced sockets 24 on the bottom edge, three f:Lat projections 25 to keep the bottom plate 6 from turning downward and to allow it to fold upward only. The left and right side plates 3, 4 are made with same mold. The left side plate 3 has out-ward spaced sockets 30 on both front and rear edges to form a hin~ed joint respective'y with the sockets 10 of the front side plate 1 and the sockets 20 of the back side plate 5 by meanæ of a pin 7. The right side plate 4 has outward spaced sockets 40 on both fron~ and .rear edges to fo~m a h~-nged joint respectively with the sockets 11 of the front side plate 1 and the back side pl~ e 2 by means of a pin 7. The let and right ~ide Plates 3, 4 have projections 3~, 41 on the top edges for snapping in t'ne siots 54, 55 of the top lid plate S, hand holes 32, 42 below the projections 31, 41, and projections 33, A~4 h,A~- ng slots 331, 431 are arranged ln such way that they are between the projections 16 of ~he rront side plate l and the p-rojections 25 of t'ne bac'~ side plate 2 after the crate is fol. ded. ~he 'op lid pla~e 5 has notches _ Co~t ~/5 12~9274 5~ anG n&en~ures _~ a~ ~'ne rea-. edge to forrl a hinged joint w~tn ~ne back side pia~e 2 '~y r.lcans of pi~s and tubular connectors, a~d slo.s 52, 53, 54, 55 in the front edge and left and right euge for the ?rojectiGrLs i2, ]3 of the front S side pla~e 1 and t'.e projections 31, 41 of tne left and right side -.~lates ~o fit in after it is closed ïne top lid plate 5 also has two small holes 56 in the front edge corresponding to the small holes 14 in the top edge of front siae plate 1, and two recesses 57 to facilita.e ~ne opening of the top lid plate 5. Six ribs 58 are provided on the top surface of the top lid plate 5 as shown in Fig. 2. Two vertical ribs 58 intersect -our horizon~al ribs 58 to form six large squares 59. The angle part 581 of each corner of the squares 59 is made a little thicker to prevent the crate stacked thereon from slipping off. The bottom plate 6 has sockets 60 on the rear edge to form hinged joint with those of the back side plate 2 by means of a pin 7, five holes 61 'or use in lifting the contents of the crate, projectior.s 62 on .he front, left and right edges to fit in the slots 161, 331, 431 of the lugs 16, 33, 43 of the front, left and right side ~lates 1, 3, 4, and two projections 63 on the front edge to strengthen the binding of the two plates 1, 6 together with the hook 15 at the bottom edge of the front side plate 1, which keeps the bottom plate from springing upward and off the front side plate 1. The knuckle pins 7 are used to join the sockets to form hinged joints. The tubular connec~ors 8 are oval in cross section and sized to fit i-n the notches 50 in the top edge of the back side plate 5 and has holes oO, 81 for the knuckle pins 7 to fi~ in and to form a hinged joint of the top lid plate 5 and the back side plate 2.
:
To assemble the crate as shown in Fig. 2, the bottom plate 6 and the back side plate 2 are first joined together by inserting the pin 7 into the sockets 60 of the bottom plate 6 and the sockets 24 of the back side plate 2 with the ~lat pro~ections 25 beside the sockets 24 supporting the bottom plate ~ and preventing the same from further Cont'd/6 openlng. T~en the lc~t and ril~ht side plates 3, 4 are hinged tog~ther with the bac~ slde plate 2 by nserting-the pins 7 in the sockcts 20, 30, ~1, 40, and having the knuckle pins 7 locked with .sn~p r~ngs at the top and bottom ends. In the same way, the left and right side plates 3, 4 are hinged together by insertinÆ the pir.s 7 nto the sockets 10, 30, 11, 40 and havlng the pins lockc~ with snap rings at the top and bottom ends. At the same time, the projections 62, 63 of the bottom plate 6 is fitted in tae slots 331, 431 of thP lugs 33, 43 of the left and right side plates 3, 4, and in the slot 161 of the lug 16 and the slots 17 in the bottom edge of the front side plate 1. As showr. in Fig. 3 the bottom plate is retained by the hook 15 at the bottom edge of the front side plate 1 and prevented from spring up. Finally, the top lid plate 5 is closed with the projections 12, 13, 31, 41 fitted in the slots 52, 53, 54, 55 as shown in Fig. 4, and wire a is inserted in the holes 56 and 14 and tied and fixed with lead or zinc at the bottom edge of the front side plate 1. Thus, the crate is ready for shipping.
As shown in ~ig. 5, the crates of this invention can be shipped in stack. The crate has a fixed ratio of length and width - 3:2 and the ribs 58 provided on the top surface intersect to form six large squares 59 of which the angle parts 581 are thicker. So the bottom of the crate on top fits the top of the crate beneat'n closely without ~ear of slip~ing off. ~nd the crates are strong enough to be shipped in a large stack without fear of damage to the contents.
It is a common practice to take out the contents one by one (or layer by layer~ when a buyer war.t to inspect the contents. Ater inspec~ion, th.ey are put bacX one by one (or layer by layer). T~ t is troublesome and timewastin~ to do so and damage would be caused to the con~ents. To eli~inate this disadvantage, the inventor developed this invention which by using of a s-mple lifting device is capable of talx-ing out or putting bacX the cont~nts quic'~'y without causing Cont'd~7 ''................................................................ .
any ~ama~_ ~o the co.it2.its. -~s s..~wn i~ ig. 6 Lhe crate is p'aced ~,-a tr.e pneumat-c li~t with its ~ive posts 102 fitted in tne i ve holes 61 in ~he boLtcm plate 6. W;.~n the crate body he,d ~y .he operaLor is 'owereG s;owiy, the contenLs b suppor.,c~ by the _-ve posts î32 a-'e noL lowered but come out of the c-.aLe. After -,.specLion by the buyer, the pneumatlc lift c is inflated anG the cra~e body held by the opera~or is pushed up pne~..atically u~til ~he contents b are fully packed in the craLe as shown ln ~ig. 7. After the top lid plate 6 is closed and tied with wire a, ~he ins?ection oper-aLion is finished. The appiication of anoth~r lifting device is shown in Fig. 3. The law of lever is applied to this lifting device which co-inprises a stand 101, five posts 102, a guide rod 104, two retaining rings 105 for retaining the guide rod 104 at .,he central post 102, and a lever 106.
The lever 106 is fitted in the rod 104 at one end and supported at the fulcru... by a post 102. With this lever 106, the crate placed on the s;ide lG3 can be raised and lowered.
Thus, the contents in the crate can be removed from the crate wi LhOU~ causing any damage.
The collapsing of crate is shown in Fig. 9. First, the wire a is cut off and the top lid plaLe S is opened as arrowed with the hand in the recess 57. After the contents sremoved, the front side plate 1 is disassembled by pulling outward the hook 15 at the bottom ed~e and letting the bottom plate 6 .urn up as arrow~d and olGed upon the back side plate 2. Then the joint of the leLt side plate 3 and the front side piate 1 is pushed rearward and ri~,htward as arrowed. At this time the righ~ side plate turns as though it was a parallelogram. It is pushed until tn~ left side plate 3 and the front side plate 1 become a straight line.
Like a ~lat board the collap~ed crate ls space saving when being shipped or stored.
